LImageViewer::GetRotateBitmapPerspectiveAngle

#include "ltwrappr.h"

L_INT LImageViewer::GetRotateBitmapPerspectiveAngle(nCellIndex, nSubCellIndex, pnAngle, uFlags)

L_INT nCellIndex;	/* index of a cell */
L_INT nSubCellIndex;	/* index into the image list attached to the cell */
L_INT * pnAngle;	/* pointer to a variable to be updated */
L_UINT uFlags;	/* reserved for future use */

Gets the perspective rotation angle of the specified cell or sub-cell.

Parameter	Description
nCellIndex	A zero-based index of the cell that contains the sub-cell, which is having its rotation angle retrieved.
nSubCellIndex	A zero-based index into the image list attached to the cell specified in nCellIndex. The perspective rotation angle of this image will be retrieved. Pass -2 to retrieve the perspective rotation angle of the image in the selected sub-cell.
pnAngle	Address of the variable to be updated with the perspective rotation angle value.
uFlags	Reserved for future use. Pass 0.

Returns

SUCCESS	The function was successful.
< 1	An error occurred. Refer to Return Codes.

Comments

To set the rotation angle of a specific cell or sub-cell, it is highly recommended to use LImageViewer::RotateBitmapPerspective instead of the standard LBitmap::RotateViewPerspective.
